Article Citation - WoS: 153Citation - Scopus: 163Predicting Energy Absorption in a Foam-Filled Thin-Walled Aluminum Tube Based on Experimentally Determined Strengthening Coefficient(Elsevier Ltd., 2006) Kavi, Halit; Toksoy, Ahmet Kaan; Kavi, Halit; Güden, Mustafa; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyThe energy absorption in a foam-filled thin-walled circular Al tube was investigated based on the experimentally determined strengthening coefficient of filling using Al and polystyrene closed-cell foams with three different densities. Foam filling was found to change the deformation mode of tube from diamond (empty tube) into concertina, regardless the foam type and density used. Although foam filling resulted in higher energy absorption than the sum of the energy absorptions of the tube alone and foam alone, it was not effective in increasing the specific energy than simply thickening the tube wall. It was shown that for efficient foam filling an appropriate foam-tube combination must be selected by taking into account the magnitude of strengthening coefficient of foam filling and the foam filler plateau load.Article Citation - WoS: 19Citation - Scopus: 19Experimental Investigation of Interaction Effects in Foam-Filled Thin-Walled Aluminum Tubes(Springer Verlag, 2006) Güden, Mustafa; Toksoy, Ahmet Kaan; Güden, Mustafa; Kavi, Halit; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyThe interaction coefficients of polystyrene foam filling of thin-walled aluminum cylindrical tubes were investigated experimentally through compression testing of partially foam-filled tubes with and without adhesive. The experimental load-displacement curves and observation of the crushed sections of filled tubes have shown that partial foam filling reduced the fold length and hence increased the average crushing loads of tubes, proving the interaction effect between tube wall and filler. The interaction coefficients for the partial foam filling were further calculated to be in the level and/or higher than that of the foam plateau load of transverse direction.
